  1. Time passed since posting or time of day? If you want to differentiate on time of day you'll need to restrict samples to 24 hour time periods since it's going to get weird when time of day loops back to midnight. But I think you could find a correlation between the rate of change in likes and the time of day. Pearson's should be good enough to attempt drawing a conclusion of whether or not the current time of day has an affect of the number of likes a person would receive during that specific time period. I would attempt to find as many data points as possible during that 24 hour period (data points being # of likes and time of day in 24h format) since I believe you have a minimum number of data points to achieve for pearson's to be "valid." But if instagram holds that kind of continuous stats you should be pretty golden.
  2. I'm seeing 1 pretty big hole that you could actually fill if you want but... Let's say a picture is posted at 1am and then the numbers of likes you record is after a few days where that 1am mark has passed multiple times. At this point you're not really recording data for when it was posted since you don't know which 1am mark you're recording from. I'm not doing a good job explaining that. Unrelated to correlation however and maybe outside the scope of SL Math is vector machines which are used with some training data in the form of 1-2 variables and then whether or not the person is a celebrity (obviously the definition of celebrity will need to be defined by you in some way). Then you can create a model, in this case, that would try and predict whether a person is a celebrity based off their number of likes they received on their pictures. Another thing I'm thinking of is making sure you restrict the pictures you look at for being less than x hours old and then record the time it was posted and the likes it received in those x hours and you can try to find a correlation of likes vs hour posted for multiple different celebrities and then explore past that. Did those celebrities post during their primetime? i.e do they post during the day or in the middle of the night? is that causing differences in the likes they received? Is instagram more popular in the US (for example) which you would see from maybe a Chinese celebrity posting in the middle of the night which would be daytime for US so maybe it gets more likes because of that?
  3. Take a 7th subject, declare what 6 you want to use towards your diploma I took all 3 sciences, my physics just didn't count...I took it for fun/potential credit from the score.
  4. Might be true on the US part. I am going off personal experience which would be US based universities.
  5. I mean, if you want to do computer science you should probably take computer science... If you want both CS and other engineering options to be open and VERY available you will be sucked into HL CS/physics/math and you'll look pretty good. Since I graduated with a computer science degree I will tell you that you will want HL CS and at least SL Math but since you had HL in both options I figure you could just do HL Math and it'll be pretty wonderful when you hit uni if you go after that CS degree https://en.wikipedia.org/wiki/Master_theorem_(analysis_of_algorithms) just gonna drop that link here if you're curious about math in a CS program...
  6. To be honest it's kind of weird that marks take until July (I think, been a few years) but then most universities are going to start fall semester in August. In fact, I'm pretty sure I had accepted an offer and had already done my initial visit to set up classes and everything else before I even knew what my IB scores were... But going directly to your question: Yes, it is always possible to wait a year before going to uni, there is nothing saying you can't. However, most scholarships you might've gotten will be gone (because they aren't just going to wait a year when they're giving you free money) and there could be a ton of other variables to make it impossible but as far as whether or not you could or could not wait for results and starting after a year: yes, you can. Want to also say that you don't have to wait a year. Universities run all of their (ok, most, there are some high level courses that any high school grad won't be getting into that aren't big enough to warrant this) every semester, nothing stopping you from starting in Spring semester after you know your scores/hopefully get into the uni you want.
  7. http://www.youtube.com/user/CampbellMitch?feature=g-user-u This is an IB teacher who has made a crap ton of IB physics videos that explains the physics and the math involved. It will likely be helpful for when you run into math problems in physics. You can google logs and exponentials although I don't seem to recall any exponentials in physics...the exponents were always set, never a variable you needed to solve for O.o
  8. Would it be better to focus in on one of his works?...assuming there are multiple, I have no idea... Or focus on one of the factors and how he uses it across all his works? I would avoid trying to prove which factors have the greatest influence. You are trying to analyze whatever your topic is so it would be more important to convey what the factors are doing and have the essay work around that instead of their influence. I don't know music so I can't help you past general advice =/

    Redox problem

    You should be able to do the titrate problem to figure out how much h2so4 reacted and then using the reaction from part a you can do some mole ratio stuff to how many moles of iron were present. Then change that to grams and divide that by 1.324g sample to give you a percent (in decimal form of course) I assumed the redox overall reaction ended up with the permanganate reaction flipped since that made more sense
  10. This book has many errors in sample problem solutions. It also has VERY awkward wording for some concepts and there were a few that my class found out to be just plain wrong. I don't know if it's because the awkward wording made it "wrong" to us or if they really meant what it said. Just a heads up about this book...
  11. The only way to quantify the color if anything is to somehow find the wavelength and/or frequency of the light it reflects. If you can't find these, you will need a new dependent variable as Ipos suggested.
  12. My mother sent me about 50 boxes of mac and cheese. Take a guess...
  13. Heck, I'm in college and still don't know >.> Since someone in this thread knows the UK well, I guess (i havent the slightest clue) I can help with the US details. Very simple. Your overall IB score will probably not matter. You will receive credit for predetermined classes based off the score you achieve in a subject. My school, for example, gave me credit for Chem 1 and 2 (6 credit hours total) because I received a 5 in HL Chem and I could then skip into Chem 3. This applies to mostly all subjects except (check with your school) physics because most of university physics is calc based and IB physics is not...at all...so most don't deem it worth credit =/ But the overall point is that for the US your GPA is what will matter. The IB scores will simply be extra credit upon admission. This applies for almost EVERY school in the US. There might be exceptions out there who are a little more accredited and actually know what IB is such as the Ivy Leagues and other top tier schools. But just like there are some who know IB and give it props...there are those who literally asked me what IB even was...
  14. Step 1: *Writing* I suck at english, so yea, read the stickies. Had to point out the irony though Sorry for the worthless post...
  15. 1) You look fine. 2) As far as I know, which is US only, most accredited universities will transfer all of your general education credits (these include your required english/behavioral science requirement for your degree. Yes you have to take courses that have near nothing directly related to your field of study). So you could, in theory, go anywhere for 1-2 years doing your "gen eds" and thus gaining a resume filled with a high college gpa rather than just high school which would look better for any application to another university that has your program. There are also graduates programs in the US. It's after your 4 years of undergraduate. Some programs, like biophysics and a few other very specific areas, are only available at the graduate level due to their specificity. 3) The US greatly depends on what university you are applying to. If I remember right there was a website that you could fill out all your basic info on (name, address, high school courses/gpa, etc) and then apply to w/e college you want. Depending on what college you choose to apply to, through the website, you will be prompted with all the required essays you would need to write. Sadly, I do not remember the website. Your counselor might know what I'm talking about though. If not, you can always just go find the applications yourself and do them individually. Honestly, in the grand idea of going to university, the time it takes for you to apply shouldn't be a factor in any of your decisions.
